Communications Perspective
From the communications perspective a public safety network is a wireless communications network used by emergency services organizations, such as police, fire and emergency medical services, to prevent or respond to incidents that harm or endanger persons or property.
Many municipalities are turning to mobile computing and other networked applications to improve the efficiency of their workforce, including public safety personnel and first responders. Consequently, public safety workers are increasingly being equipped with wireless laptops, handheld computers, and mobile video cameras to improve their efficiency, visibility, and ability to instantly collaborate with central command, coworkers and other agencies. Video surveillance cameras and unattended sensors are becoming important tools to extend the eyes and ears of public safety agencies. A pilot study along the US-Mexico border uses a wireless mesh network.
The need to access and share this vital new flow of data and images is driving investments in a new kind of network: broadband wireless mesh networks using Wi-Fi, WiMAX, and 4.9 GHz public safety radio frequencies. These networks are metropolitan or regional in scope, can maintain connections with highly mobile workers, deliver large amounts of low-cost bandwidth with extremely high reliability, and support real-time video, voice and data.

Famous quotes containing the word perspective:
“The fact that illness is associated with the poor—who are, from the perspective of the privileged, aliens in one’s midst—reinforces the association of illness with the foreign: with an exotic, often primitive place.”
—Susan Sontag (b. 1933)
